LIGHT-SHADE HOLDER.

Qpecification of Letters Patent. I

Application filed April 12, 1917. Serial No. 161,577.

To all whom it concern:

Be it known that we, "WILLrA u H. PEAR- SON and JOHN L. OEFINGER, cltizens of the United States, and residents of the city further object is the production of a shade holder which will be of durable and economical construction, of neat and finished appearance, and which will be highly efficlent in use. Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawin forming a part of this specification, and 1n Figure 1 is 3' central "vertical section "through'a light shade holder embodying the invention, showing the same applied for use in connection with an electric light a socket,

Fig. 6, a sectional view through the up per portion of the member shown in Fig. 5, showing, in addition, the retainer ring which cooperates therewith, said retainerrmg being shown in section,

-- Fig. 7, a bottom plan view of said retainer Fig. 8, a .view similar to Fig. 6 showing a slightly modified form of the retainer rmg Fig. 9, a central section through another form of the holder, and

Fig. 10, a-bottom plan view of Fig. 9.

The preferred form of construction as illustrated in Figs. '1 to 8 inclusive, comprises a shade-engaging element which consists of a clamp portion 11 which is of annular form and split, the same being adapted to snugly embrace an electric lamp socket 12 of conventional form as seen in Fig. 1.

' Said clamp 11 is formed with an annular internal groove '13 which is adapted for engagement with the annular external bead 14 onthe socket 12, the arrangement being such that, when the groove 13 is engaged with said bead, the clamp 11 will be held against longitudinal shifting on the socket.

Cooperating with the clam 11 is an annular retainer 15 the latter being of channel form with the channel opening inwardly. Said. retainer is of an internal diameter such as to permit of slipping of the same' over the bead 14 of the socket 12 without interruption. Formed at intervals on the Patented Feb. is. rare.

clamp 11 are outwardly extending projections 16 and formed in one edge or side of the retainer 15 are notches or slots 17 adapted to register with and permit the passa e of the projections 16 so as to permit of shi ting of .one edge of said retainer over said projections and over the grooved portion 18 When. said retainer is thus engaged w1th the clamp 11 it will be seen that the latter will be positively held against expan- SlOIl and thus positively prevented from movement on the socket 12. In order to v lock the retainer in operative relation with the clamp 11 it is only necessary, after the same has been shifted into engagement with the projections 16, to rotate said retainer to efl'ect non-registration of the notches therein relative to projections 16. Said retainer, when thus positioned, will of course be locked against shifting from engagement with the clamp, shifting of said retainer from engagement with the clamp being permitted only uponrotation of the retainer to a position in which the notches 17 thereof will register with the projections 16, in which event theretainer may be shifted as desired without interruption. In order to yieldingly' hold the retainer in operativerelation with the clamp 11 in a position in which'the notches thereof are out of registration with the projections 16,. said retainer is formed with inwardly extending engaging portions '18 which may be pressed therein as shown in Fi s. 6 and 7. Said portions 18 are forme withrecesses 19 adapted, upon rotative adjustment of the retainer, to enga e with, projections 16 as clearly illustrated 1n Fig. 6. The engagement of portions 18 with the projections 17 is a yielding-one as will be seen, it being possible to rotate said retainer when suflicient pressure is applied thereto to overcome the frictional engagement between the parts. If desired reoessed fingers 18 may be employed WlllCh will be formed separate from the retainer ring and secured therein by soldering or otherwise as seen in Fig. 8.

"Formed integral with and projecting radially from one edge of the clamping rlng 11 are supporting arms 20 the outer ends of which are angularly bent to embrace the upper outwardly flaring edge portion of the conventional shade 21, as clearly seen in Fig. 1. The engagement of the arms 20 with the shade is a yielding one, said arms being adapted to flex outwardly in order to permit of detachment of the shade. However, in order to lock said arms against such outward flexing so as to permit of detachment of the shade, an annular retainer .22 is provided which is adapted to be shifted into engagement with the outer ends of said arms as clearly seen in Fig. I. Said retainer is formed with an annular internal groove 23 which is adapted for engagement with outwardly projecting beads 24 formed in the arms 20, the arrangement being such that when said groove is in engagement with said heads, the retainer willbe frictionally held and thus retained in operative relation with arms 20. Downward movement of the annular flange 25 which is adapted to engage against the upper sides of arms 20 as clearly seen in Fig. 1.

In the form of the construction shown in Figs. 9 and 10 the invention isshown applied to the conventional form of canopy or bell-shaped electric light fixture which is illustrated at 26. In this arrangement the outer end ofthe member 26 is formed with engaging arms 20' of the same form as the outer ends of arms 20 in the construction illustrated in Fig. 1, the members 20 being adapted for engagement with the light shade in precisely the same manner as the arms 20 above described. 'A retainer ring 22 of precisely the same form as above described is provided for cooperation with the arms 20 as will be readily understood.

With the construction set forth it will be 'seen that a light shade holder is provided in which the use of'screws is positively eliminated, and in which the holder may be applied to a light socket, and the shade to the holder with ease and expedition. Also in the construction set. forth the engagement with the light shade is a yielding one, that is engaging arms 20 are adapted to yield sufliciently to permit of expansion and contraction of the shade under different temperatures. Thus with this arrangement the danger of cracking of the shade through too tight clamping of the same as frequently results where screws are employed or a rigid connection with the shade efiected asis the case at present, will be positivelv eliminated.

While We have illustrated and described the preferred forms of construction for carrying our inventioninto eflect, these are capable of variation and modification with out departing from the spirit of the invention. We, therefore, do'not wish to be limtached; an annular retainer adapted to em- .brace said clamp to hold the same in clamping relation with the/element engaged; and means for locking said retainer in operative relation with said clamp, said means comprising projections on said clamp, said retainer having slots adapted to register with and receive said projections, and said retainer at both sides of each of said slots being sloped inwardly toward the slot, substantially as described.

A light shade holder comprising a shade engaging portion; an annular split clamp operatively connected with said shade-engaging portion andv adapted to embrace the element to which the holder is attached; an annular rotatably adjustable retainer adapted to embrace said clamp to hold the same in clamping relation with the element engaged; and means for locking said retainer in operative relation with said clamp, said means comprising projections on said clamp, said retainer having slots adapted to register with and receive said projections, and said retainer at both sides of each of-said slots, and circumferentially of the retainer being gradually sloped inwardly toward the slot, substantially as described.

3. A light shade holder comprising a shade-engaging portion; an annular split clamp operatively connected with said shade-engaging portion and adapted to embrace the element to which the holder is attached; an annular rotatably adjustable retainer adapted to embrace said clamp to tainer in operative relation with said clamp,
